It was announced by scientists that traces of air pollution from 16th century conquistadors were found in ice from the Peruvian Andes. The mining conquistadors left behind an impressive amount of pollution that can now be analyzed to learn more about those people.

Even though the imprint of smog, which was found to be very metal-rich, was found in Peru, scientists are certain that the pollution originated from what is now Bolivia, hundreds of miles away, at the mines in Potosí.
